If you don't need all of the features of TurboTax Self-Employed, you can downgrade from TurboTax
Self Employed to the Deluxe version of TurboTax Online, as long as you haven't paid yet (or
registered in a free version) - but please bear in mind that, yes, you will need to clear any data which you have entered
and start over in the other TurboTax version.
Please see
the following TurboTax FAQ,
"Can I switch to a lower-priced version of TurboTax
Online?":
